|how do you know when shrubs and trees are damaged from winter cold/frost?
When can they be trimmed or do you wait for them to grow back?
|Frost usually turns the foliage crispy brown or black on susceptible plants. If your plants look normal, they suffered no damage. If the leaves are crispy and off-color, they probably got nipped by the frost. Common advice is to wait until the third week of February before pruning away any frost damage. The reason for waiting is that there is still a chance of another bout of frosty weather. When it's time to prune, cut back a few inches past the frost damage and new growth will emerge from below the pruning cuts. Best wishes with your landscape.|
